DETAILED DESCRIPTION

Apparatuses, machine-readable media, and methods related to hazard indicators are described. Determining whether hazards exists and the location of a hazard can be helpful when moving about. Computing devices (e.g., mobile devices and/or cloud-based computers) can be configured to run an application (e.g., a hazard indication tool) to determine that a hazard exists and indicate to a user of a computing device that the hazard exists according to examples of the present disclosure. A user can carry a mobile device with them while they are walking or running. The mobile device can include a number of sensors (e.g., image sensors, microphones, infrared (IR) sensors, ultrasonic sensors, location sensors) to generate data that can be used by a hazard indication tool to determine if a hazard exists. The hazard indication tool can output a warning that indicates to a user that a hazard exists, an alternate route to avoid the hazard, and/or generate a hazard library that other users can use to obtain information about hazards.

A mobile device can be carried by a user and include a number of sensors. The number of sensors can collect data, such as image, audio, infrared (IR), ultrasonic, and/or location (e.g., GPS) data, among other types of data. The data from the sensors can be used by the hazard indication tool to determine if a hazard exists. For example, image data can indicate that a road and/or sidewalk is under construction, which would be a hazard that the user would want to avoid. Another example can include that audio and/or image data can indicate that an emergency, such as a medical or fire emergency, is taking place and is a hazard that the user would want to avoid. Another example is that image data can indicate that the user is approaching an immediate hazard, such as entering an intersection with traffic or veering off a sidewalk. The image data capture by the user's mobile device can be used by the hazard indication tool to determine that the user is approaching an immediate hazard. The hazard indication tool can provide a warning of the immediate hazard to the user via an audible warning, such as an alarm, a vibration warning that causes the user's mobile device to vibrate, and/or a visual warning, such as a flashing indicator on the display of the user's mobile device.

The hazard indication tool can provide a warning to the user that the hazard exists and provide an alternate route to for the user to take to avoid the hazard. The hazard indication tool on a user's mobile device can give an audible warning when a user is approaching a hazard. For example, the hazard indication tool can cause the mobile device to sound an audible warning that states “2^(nd) Avenue is closed between 5^(th) and 7^(th) Streets, please proceed to 3^(rd) Avenue to avoid this closure.” The hazard indication tool can also provide a map for the user to view on their mobile device that indicates where the hazard is located, the type of hazard, and an alternate route to avoid the hazard.

The hazard indication tool can create a hazard library that includes information about the hazard's detected by the hazard indication tool. The hazard library can be available to other users that are using the hazard indication tool on their mobile devices. For example, when the hazard indication tool determines that hazard exists, such a fire emergency, using image and audio data from a user's mobile device, the hazard indication tool can create this hazard in the hazard library and send a warning to other users of the hazard indication tool that are near the hazard.

In the following detailed description of the present disclosure, reference is made to the accompanying drawings that form a part hereof, and in which is shown by way of illustration how one or more embodiments of the disclosure can be practiced. These embodiments are described in sufficient detail to enable those of ordinary skill in the art to practice the embodiments of this disclosure, and it is to be understood that other embodiments can be utilized and that process, electrical, and structural changes can be made without departing from the scope of the present disclosure.

As used herein, designators such as “N,” “M,” etc., particularly with respect to reference numerals in the drawings, indicate that a number of the particular feature so designation can be included. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, the singular forms “a,” “an,” and “the” can include both singular and plural referents, unless the context clearly dictates otherwise. In addition, “a number of,” “at least one,” and “one or more” (e.g., a number of memory devices) can refer to one or more memory devices, whereas a “plurality of” is intended to refer to more than one of such things. Furthermore, the words “can” and “may” are used throughout this application in a permissive sense (i.e., having the potential to, being able to), not in a mandatory sense (i.e., must). The term “include,” and derivations thereof, means “including, but not limited to.” The terms “coupled,” and “coupling” mean to be directly or indirectly connected physically or for access to and movement (transmission) of commands and/or data, as appropriate to the context. The terms “data” and “data values” are used interchangeably herein and can have the same meaning, as appropriate to the context.

The figures herein follow a numbering convention in which the first digit or digits correspond to the figure number and the remaining digits identify an element or component in the figure. Similar elements or components between different figures can be identified by the use of similar digits. For example, 120 can reference element “20” in FIG. 1, and a similar element can be referenced as 220 in FIG. 2. As will be appreciated, elements shown in the various embodiments herein can be added, exchanged, and/or eliminated so as to provide a number of additional embodiments of the present disclosure. In addition, the proportion and/or the relative scale of the elements provided in the figures are intended to illustrate certain embodiments of the present disclosure and should not be taken in a limiting sense.

FIG. 1 is a functional diagram representing an example system for a hazard indicator in accordance with a number of embodiments of the present disclosure. The system can include inputs 120-1, 120-2, 102-N from computing devices of a number of users. Inputs 120-1, 120-2, 102-N can be sensor data from mobile devices of a number of users and/or data that is manually input by users into the mobile devices of the users.

The hazard indication tool 110 can be located on a computing device, such as a computing device of user and/or a cloud based computing device that is wirelessly coupled to the computing devices of users. Hazard indication tool 110 can be an application that is run using processing resources and/or memory resources of a computing device. Hazard indication tool 100 can received inputs 120-1, 120-2, 102-N from a number of users and determine whether a hazard exists and details about the hazard, such as the type of hazard, the location of the hazard, an amount of time that the hazard has existed or will exist, among other details.

Hazard indication tool 110 can output a warning 130 to users of the hazard indication tool that a hazard exists. The warning 130 can be an audible warning, a visual warning, and/or a vibrating warning, for example. An audible warning can cause the speakers on a user's mobile device to sound an alarm or to provide details to the about the location and type of hazard. For example, warning 130 can indicate to a user that they are approaching a protest and/or demonstration that is block pedestrian and/or automobile traffic. Also, warning 130 can be alarm that is sounded by the user's mobile device or a flashing indicator on the display of the user's mobile device to indicate that that user is approaching an immediate hazard, such as entering an intersection with traffic.

Hazard indication tool 100 can output an alternate route 132 to users of the hazard indication tool to allow the users to avoid a hazard. The alternate route 132 can be indicated on a map on the user's mobile device. For example, the alternate route can show the hazard on the map, provide details regarding the type of hazard, such as when the hazard was identified and how long the hazard is expected to remain, and provide a route on the map to avoid the hazard.

Hazard indication tool 110 can create a hazard library 140. Hazard library 140 include information regarding the hazards that the hazard indication tool 110 has detected. Hazard library 140 can include the type of hazard, the location of the hazard, the day and time that the hazard was identified, and how long the hazard is expected to remain, among other types of information regarding the hazards. Hazard library 140 can be used by the hazard indication tool 110 to inform and warn users of the hazard indication tool 110 that they are approaching a hazard. For example, hazard indication tool 100 can receive location data from a user and compare the location data to location data of hazards in hazard library 140. If the user is approaching a hazard in the hazard library 140, the hazard indication tool 110 can send a warning 130 of the hazard to the user and/or send an alternate route 132 to the user so the user can avoid the hazard.

Hazard library 140 can also be accessed by users of the hazard indication tool 110 to locate hazards before the users begin traveling a route. For example, a user can use the hazard library 140 to locate hazards in a particular area and determine whether or not they need to avoid the particular area based on the information regarding hazards in the hazard library. The information in the hazard library 140 can also be used by the hazard indication tool 110 to generate alternate routes 132 for a user to take to avoid hazards before the user begins their journey.

FIG. 2 is a diagram representing example of inputs 220 for a hazard indicator in accordance with a number of embodiments of the present disclosure. A hazard indication tool can receive inputs 220 to determine whether a hazard exists and determine information regarding a hazard. Inputs 220 can include data from sensors on a user's mobile device. Inputs 220 can include image data 221 from a user's mobile device. The image data 221 can be video data and/or photographic data. An image sensor from a user's mobile device can provide image data to the hazard indication tool that provide information regarding the surroundings of a user. For example, the image data 221 can provide panoramic image data that indicates the user is entering an intersection with approaching traffic. Also, image data 221 can provide information to indicate that an emergency vehicle is present or that the user is approaching traffic congestion.

Inputs 220 can include infrared (IR) data 222 from a user's mobile device. An IR sensor from a user's mobile device can provide IR data to the hazard indication tool that provide information regarding the surroundings of a user.

In some examples, the processing resource 462 and memory resource 464 comprise a system 460 such as a hazard indicator tool (e.g., hazard indicator tool 110 illustrated in FIG. 1).

The system 460 illustrated in FIG. 4 can be a server (e.g., a cloud-based computing device) and/or computing device (e.g., a mobile device), among other computing device and can include the processing resource 462. The system 460 can be coupled to other systems and/or computing devices (e.g., coupled via a wireless network). The system 460 can further include the memory resource 464 (e.g., a non-transitory MRM), on which may be stored instructions, such as instructions 465, 466, 467, 468, and 469. Although the following descriptions refer to a processing resource and a memory resource, the descriptions may also apply to a system with multiple processing resources and multiple memory resources. In such examples, the instructions may be distributed (e.g., stored) across multiple memory resources and the instructions may be distributed (e.g., executed by) across multiple processing resources.

The memory resource 464 may be electronic, magnetic, optical, or other physical storage device that stores executable instructions. Thus, the memory resource 464 may be, for example, non-volatile or volatile memory. For example, non-volatile memory can provide persistent data by retaining written data when not powered, and non-volatile memory types can include NAND flash memory, NOR flash memory, read only memory (ROM), Electrically Erasable Programmable ROM (EEPROM), Erasable Programmable ROM (EPROM), and Storage Class Memory (SCM) that can include resistance variable memory, such as phase change random access memory (PCRAM), three-dimensional cross-point memory, resistive random access memory (RRAM), ferroelectric random access memory (FeRAM), magnetoresistive random access memory (MRAM), and programmable conductive memory, among other types of memory. Volatile memory can require power to maintain its data and can include random-access memory (RAM), dynamic random-access memory (DRAM), and static random-access memory (SRAM), among others.

In some examples, the memory resource 464 is a non-transitory MRM comprising Random Access Memory (RAM), an Electrically-Erasable Programmable ROM (EEPROM), a storage drive, an optical disc, and the like. The memory resource 464 may be disposed within a controller and/or computing device. In this example, the executable instructions 465, 466, 467, 468, and 469 can be “installed” on the device. Additionally, and/or alternatively, the memory resource 464 can be a portable, external or remote storage medium, for example, that allows the system to download the instructions 465, 466, 467, 468, and 469 from the portable/external/remote storage medium. In this situation, the executable instructions may be part of an “installation package”. As described herein, the memory resource 464 can be encoded with executable instructions for indicating a hazard.

The instructions 465, when executed by a processing resource such as the processing resource 462, can include instructions to receive at the processing resource 462, the memory resource 464, or both, a plurality of input data from a plurality of sources, the plurality of sources comprising mobile devices of users. In some examples, the plurality of input data can include, or any combination thereof. For instance, data may be manually entered via an application of a mobile device for sending to the processing resource 464 or automatically (e.g., with little or no human intervention) to the processing resource 464.

The instructions 466, when executed by a processing resource such as processing resource 462, can include instructions to identify a hazard. For instance, processing resource 464 can identify a hazard based on the plurality of input data. In some examples, the instructions can be executable to identify a hazard, based on received input data from the mobile device of the users.

The instructions 467, when executed by a processing resource such as the processing resource 462, can include instructions to output a warning that indicates a hazard exist. The instructions can output a warning in the form of an audible warning, such an alarm or words that are spoken to describe the hazard, for example, and/or a visual warning, such as a flashing light or an indication of the location and the type of hazard on a map, for example.

The instructions 468, when executed by a processing resource such as the processing resource 462, can include instructions to output a route to avoid the hazard based at least in part on the input data and the identification of the hazard by the processing resource 462.

The instructions 469, when executed by a processing resource such as the processing resource 462, can include instructions to generate a hazard library that includes location, type, and/or temporal data associated with the hazard that are identified by the processing resource 462. The hazard library can be communicated to and/or accessed by other users such that the other users may be made aware of hazards that they may be approaching and may be provided an alternate route to avoid the hazard. The hazard library can be stored in memory resource 464. The processing resource 462 can include instructions to receive location of data of other users and provide a warning and/or an alternate route to users in response to the processing resource 462 executing instructions that users are approaching hazards that are stored in the hazard library.

FIG. 5 is a flow diagram representing an example method for indicating a hazard in accordance with a number of embodiments of the present disclosure. In FIG. 5, users 570-1, 570-2, and 570-M can provide inputs 520 to a hazard indication tool.
